Air pollution device

ABSTRACT

A natural gas burning device for preventing air pollution. This device serves to completely burn smoke particles, carbon, sulfurgases and the like that have been accumulated by the burning of coal and garbage. The device includes a gas jet above the furnace containing the garbage and coal, the gas burner serving to completely burn the smoke particles and gasses.

It is therefore the primary purpose of this invention to provide an apparatus which will substantially reduce air pollution produced by smoke stacks and the like.

Another object of the present invention is to provide a device or apparatus of the type described which will include a burner above the furnace within-its chimney which will have an automatic shut-off portion which will cut off the gas burner within the chimney of the apparatus when garbageand coal are not burning.

A further object of this invention is to provide an apparatus which will be above the flames that are burning the garbage and coal, the jet-like flames being of sufficient heat to completely burn the smoke particles and gasses produced by the incomplete burning normally found within furnaces.

Other objects of the present invention are to provide an air pollution prevention device which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will become readily evident upon a study of the following specification together with the accompanying drawing wherein:

The drawing is the sole view of the present invention.

The FIGURE shows a side elevation, partially broken away, of my incinerator and afterbumer.

According to this invention, an air pollution prevention apparatus '10 is shown to include a hollow cylindrical furnace 11 supported upon legs 12. A natural gas burner 14 is secured within the chimney 13 above furnace 11 and is provided with an automatic shut-off device 15 which serves to shut off the burner 14 when garbage 16 or the like is not being burned. The furnace 11 is provided with a door 17 for the entrance of garbage 16 and the coal 18 enters the port 18' in alignment with pipe 19. Pipe 19 is parallel with pipe 20 which carries air 21 which is blown into furnace 11 by means of blower 22 which is of the conventional type. The coal 18 is carried within the coal bin 23. A chute 24 secured to bin 23 at its top, is also secured to the upper extremity of the coal hopper 25, the coal 18 being fed into furnace 11 by means of apparatus 26 which is well known in the art.

As the flames 27 within furnace 1 l are burning the garbage l6 and the coal 18, the natural gas is fed to the gas burner 14 and is ignited in the well known manner. The gas serving to completely burn the smoke particles produced by flame 27 and also the carbon, sulfur gases and the like that are accumulated by the incomplete burning of coal l8 and garbage 16.

It shall be noted that the automatic shut-off device 15 will cause the gas burner to shut off when flames 27 are not produced, the action being stopped by common thermalstatic controls within the automatic shut-off device 15 (not shown).

What I now claim is:

1. An air pollution prevention apparatus comprising in combination, a cylindrical furnace for receiving garbage and coal, a chimney carried by said furnace with a natural gas burner on the interior of said chimney for providing sufficient heat to burn smoke particles and other gases, automatic shut-off means carried by said burner for stopping the burning of the gases at said burner when garbage and coal are not being consumed by flames within said furnace, pipe means carried by said device for coal and air, blower means carried by said apparatus and means for feeding said coal into said furnace, said furnace being provided with door means for the entrance of garbage into said furnace, said burner being spaced above the horizontal structure'of said furnace, said burner being positioned over the flames produced by the burning of said garbage and said coal, said coal being pushed into pit means of said furnace by said feeding apparatus, said feeding apparatus comprising a chute between a coal bin and an upper end of a hopper for delivering coal to said hopper said hopper being connected by said pipe means to said pit means.

2. The combination according to claim 1 wherein port means adjacent to and separated by wall means between said coal pipe and said air pipe provide for the separate Introduction of coal into said furnace and a separate introduction of air into said furnace, said air being blowned by blower means at said hopper, and an automatic shut-off device being provided to ether with said natural gas burner in said chimney, said automatic shut-off device having means to respond to the heat of said flames for automatically activating said burner, the heat from said burner being sufficient to completely impure gases and smoke particles.

3. The combination according to claim 2 wherein said gas burner is located strategically, said automatic shut-off device being positioned at said burner and extending through said chimney of said apparatus and the port of said furnace receiving air being provided with a plurality ofysmall openings, said openings preventing the coal and garbage from falling into said pipes supplying said air, said bore providing sufficient pressure to keep said garbage and said coal from entering said openings of said port receiving said air.
